Ta all whom it mayconcem:

Be it known: thatl THOMAS H. IIERR, a citizen of the United-States, and. a resident of"@0lumbus; in the county ofFra-nklinand State ofOhi'o', have made. a new and useful intention in Meter Supports, of which the following is a specification.

This invention relates to gage or meter supports and'has for an obj'ect'to, produce simple and easy means for mounting and leveling a meter, or gage.

ri'fice, meters. indicate the pressure of a gas or fi'ui'dfat a point'in the line of" normal flow and also the pressure at apoint in the line, of" increased velocity of flow; These pressure differences: and the static pressure iii-.the line are. empl'oye'din" computing the volume of fluid flowing. througlithe line. The pressures above mentioned :are communi'cated toth'e pressure chamber of :the differential gage through relatively small; pipes or passages and it is, therefore, desirable to locate the-gage; as close to the line as-convenientfor the pu-rposeof avoiding: variations in the pressures transmitted occasioned bythe pressure-t-ransmitt-ingpipes or passages. t is customaryto mount-orifice meters; directly on -the gas main or line through which the fluid to be; met-eredflows. This is usually doneby-mounting a saddle 0n the main and then mounting the differential gage on the saddle or on ;a: sup-portcarried by the saddle. No matter- -what'-means. are

sential foritte stand level and-an object of this invention is to provide simple-and effectix 'eameansfon easily and quickly leveling the meter on its support.

The above mentioned objectsyand 'othei" objects which will be madernore-apparent throughout the furtherdeseription of the invention, are attained by means of the apparatus embodying the features herein illustrated and described in the drawings forming a part hereof.

' In the drawings, Figure 1 is a front view of an orifice meter mounted on a gas main and illustrates a support embodying my invention. Fig. 2 is a fragmental view of the gage shown in Fig. 1, on an enlarged scale, and illustrates my improved means for mounting and leveling the gage a portion of the apparatus being shown in section for convenience of illustration. Fig. 8 is a fragmental side elevation of the apparatus illussecured to the saddle anda to the pedestal.

'tratedin Fig; 2, a portion being shownin section for convenience. of illustrations WFhile'my invention is applicable to gages of other types, I'liave illustrated it in connection with a' well-known form of orifice meter. As shown, the diffe'rentialanch static main 5; As shown, the saddle is secured to the main bymeans offu-shapedbolts or straps'9. The pedestaffi'may consist; ofa

section of pipe and the saddle is provided With a: tapped lug into which the pedestal is screwed; Thesupp'ort 8ishoiv-n'isiprovided with a tapped aperture andis screwed onto the upper end ofthe pedestal? The gage is secured 111 place on the support by means of a coupling bestillustrated'fin Fig. 2'; The

coupling includes a pin 10 having acylinfdrical shank adapted ftoprojfectup ardIy through a cylindrical aperture formed in; the base plate 11" ofithej support and through a cylindrical aperture 12 formed" in the casingiofthegage. The'pinis provided in its shank with. a transverse aperture adapted to receive a locking pin or bar l31: Theaper tureis .so locatedin the shank'thfat thelo'cking employed for mounting the gage; it is, es-

12."th'rough which thepin'proje'cts. The heajd of the pin 10" isfOrmed 'With 'a' partially splieri'cal surface which is engagedby a semi-spherical socketformed in. the-lower face of the. plate Ilandflis therefore capable of" being tilted to different, positions .with relation tothe plate. A pin 13' is located in suitable apertures formed in the support 8, and holds the pin in place. lVith this arrangement, the engagement of the ballshaped head of the pin with the socket in the lower faceof the base plate 11 and the engagement of the bar 13 with the inner face of the casing 12" positively locks the gage to the support 8. The aperture 12 and the aperture in the plate 11 through which the shank of the pin projects are preferably of greater diameter than the shank ofthe pin 10 so that the gage casing may be moved to different angular positions with relation to the pin during the operation of adjusting the position and rigidly mounting the gage on the support. The support is also provided with mounting and leveling screws 14, whichare shown threaded into the overhanging portion of the base plate 11 of the support 8 and which are adapted to abut against suitable lugs 15 formed on the gage casing. The device illustrated in the drawings is provided with three such screws and cooperating lugs and the gage casing is, therefore, provided with a three-point support. Dun ing the operation of leveling and rigidly mounting the gage in place on its support, the pin 10 and locking bar 13 are placed in the positions illustrated and above described. The three screws 14: are then manipulated so that they raise the gage casing above the plate 11 and move the head of the pm 10 into engagement with the socket formed in the lower face of the plate 11 by the lift ing force imparted to the pin through the engagement of the locking bar 13 with the inner face of the casing 12. With the parts arranged as described and illustrated, the pin 10 operates as a tension member, whereas the screws 14 operate as struts or supports and the casing 12 may be swung to diiterent angular positions relative to the surface of the support 8 for the purpose or leveling the gage. This is accomplished by screwing up one or more of the screws 14: and backing off other set screws until the casing is level and at the same time rigidly secured to the support. The top of the meter casing may be provided with spirit levels 16 for facilitating the leveling operation.

Fluid pressure is transmitted from the main through the relatively small pipes 17, 1'7 and in the case of an orifice meter the connections between these pipes and the main are suitably located with relation to the orifice in the main. It will be apparent that the pipes 17 and 17 are sufficiently long to permit sufficient flexure to accommodate the leveling of the meter without imposing undue strains on the pipe connections.

While I have illustrated but one embodiment of my invention, it will be apparent that various changes and modifications may la r/sis be made therein without departing from the spirit and scope of the invention as set forth by the appended claims and that the invention may be adapted for use in connection with any type of gages and it is, therefore, not limited to orifice meters.

1 claim as my invention:

1. In combination with a pipe line, a saddle seated on or secured to the pipe line, a pedestal secured to the saddle, a gage support secured to said pedestal, a gage pivotally secured to said support, and mea-nsbetween said gage and said support for leveling the gage and rigidly holding it in level.

In combination with a pipe line, a saddle seated on and secured to the pipe line, a pedestal secured to the saddle, a gage support element secured to the pedestal, a gage casing element, a pin loosely engaging one of said elements and having a ball-shaped head engaging a socket formed in the other element, anda plurality of adjusting screws between said elements for subjecting said pin to strain and for adjusting the position of the casing element with relation to the support element and for rigidly holding the casing element in the adjusted position.

3. In combination with a pipe line, a saddle partiallysurrounding said line, means for securing said saddle in place on the line,

a pedestal rigidly mounted on said saddle, a support element rigidly mounted on said pedestal, a gage casing element mounted on said support element, a pin loosely engaging one of said elements and having a ball-shaped head engaging a socket formed in the other element, adjusting screws between said elements for subjecting said pin to tension and for adjusting the position of the casing element with relation to the support element and for holding the elements in adjusted position.

In testimony whereof, I have hereunto subscribed my name this 23d day of July, 1921.
